parts of class being skipped :(

Please forgive my limited knowledge on puppet. I need some assistance in achieving what most of you would consider a very simple task.
I am attempting to install zabbix agent below and modify the configuration file then reload the service. I believe the code is incomplete but i am not sure where the problem is because the agent run in not generating an error. from analysis the package is installed and the service is enabled then nothing else.

My thought process for the class is a follow.
1.Create a repo on the servers
2. install zabbix agent
3. modify the config file
4. reload the service.

The code can be seen below. Thank you in advance for any assistance i really appreciate it.
